Preferably, in a normal working state of the mower, the first magnetic block is close to the first reed switch, so that the first reed switch is in a closed state; when the working state of the mower changes, the first magnetic block is far away from the first reed pipe, the first reed pipe is opened, and the first lifting detection plate generates current signal changes. Therefore the utility model discloses use the magnet type to hang and promote the operating condition that detection component monitored lawn mower to utilize the relative position between first magnetic path and the first tongue tube to change, make first promotion pick-up plate produce the current signal and change (be the detected signal), so that control assembly controls lawn mower stop work and reports to the police according to this current signal change, have that the principle is simple, be difficult for producing a large amount of electromagnetic radiation, safer, and reduced advantages such as the cost of device.
Meanwhile, for the automatic reset of the suspension lifting detection assembly, after the control assembly changes the working state of the mower, the automatic reset of the suspension lifting detection assembly can be realized in the following manner so as to carry out the next detection action. Namely, the fixed ripple cover 350 is hung and fixed by being sleeved outside the hanging spring 330; one end of the suspension fixing corrugated sleeve 350 is clamped on the suspension ball head 310, and the other end of the suspension fixing corrugated sleeve is fixedly arranged on the shell of the mower through a suspension fixing frame 360; when the lifting limiting member moves upwards, the suspended fixed corrugated sleeve 350 is stretched, so that the restoring pulling force can be generated, and the sealing protection effect can be achieved. Of course, in order to increase the restoring force of the suspension and lifting detection assembly, the suspension and lifting detection assembly 300 for a lawn mower further includes a suspension and restoring spring 370 sleeved outside the lifting limiting member 320; two ends of the suspension return spring 370 respectively abut against the bottom of the suspension fixing frame 360 and the bottom of the lifting limiting piece 320; when promoting the locating part upward movement, hang mount 360 and keep motionless, lead to hanging mount 360 to promote the spacing between the locating part bottom and diminish, hang reset spring 370 and be compressed, produce the elasticity that resets, after lawn mower stop work, to hanging promotion determine module and reset, avoid it to appear blocking the shell phenomenon.
(2) When the movable upper cover of the mower moves horizontally, the movable upper cover drives the second magnetic block to be away from the second reed pipe, current change is generated on the second lifting detection plate, the current signal change is transmitted to a control assembly of the mower, and the control assembly controls the mower to adjust a circuit or stop working.
The above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present invention.

when the movable upper cover and the shell generate relative displacement in the horizontal direction, the second magnetic block is close to or far away from the second reed pipe, and the second reed pipe is opened or closed, so that a current signal on the second lifting detection plate is changed; and
the second lifting detection plate is electrically connected with the control assembly so as to send the current signal to the control assembly as a detection signal.
